Operation Dragoon was the Allied invasion of southern France on 15 August 1944, during World War II. The invasion was initiated via a parachute drop by the 1st Airborne Task Force, followed by an amphibious assault by elements of the U.S. Seventh Army, followed a day later by a force made up primarily of the French First Army. The landing caused the German Army Group G to abandon southern France and to retreat under constant Allied attacks to the Vosges Mountains. Despite being a large and complex military operation with a well-executed amphibious and airborne component, Operation Dragoon is not well known; it came in the later stages of the war and was overshadowed by the earlier and larger Operation Overlord.
